SPECIFICATION forming part of Letters Patent No. 645,096, dated March13, 1900.

Application led April 7, 1899. Serial No. 712,185. (No model.)

T @ZZ whom it may concern:

Be it known that I, Louis A. HOERR, a citt zen of the United States,residing at St.Louis, in the State of Missouri, have invented a new anduseful Improvement in Seal-Locks and Analogous Devices, of which thefollowing is a specification.

My invention relates chiefly, but not entirely,`to seal-locks for cars;and the chief object of my improvements is to provide a seal-lock whichwill combine strength, efficiency, and durability with great simplicityand cheapness. I achieve that object by mechanism of which two forms areillustrated in the accompanying drawings, in which- Figure 1 is a frontelevation of a preferred form of seal-lock embodying my improvements.Fig. 2 is a plan view. Fig. 3 is a front elevation of a detail. Fig.4 isa detailed isometric projection of the front of the preferred form ofhasp. Fig. 5 is a detailed rear end view of the hasp. Fig. 6 is anenlarged detailed View of the back of the preferred form of hasp-head.Fig. 7 is a front end elevation of a modification of my device. Fig. 8is a plan View of the same, and Fig. 9 is a detailed view of the form ofkeeper illustrated in Figs. 7 and 8.

Similar letters referto similar paris throughout the several views.

A represents a car-door, B a door-post, and B a batten, all of ordinaryconstruction.

C represents a staple of com mon form.

D represents my improved hasp, which is shown pivoted at CZ upon thestaple C.

In the preferred form of my hasp D represents the base; d',strengthening ribs or webs; D2, an inwardly-turned head whose face d2 ispreferably made concave, as shown, so as to prevent its not fitting itskeeper by reason of roughness incident to casting, and which ispreferably provided with a backwardlyextending wing (Z3 and aforwardly-extending wing d4. The outer edge d5 of the former is curvedinwardly, and the outer edge d6 of the latter is curved outwardly,substantially in the arcs of the circles in which they respectivelyswing, and the rear side d? and the front side d3 of the hasp-head arepreferably curved in arcs ofA circles substantially parallel with thecurves of the outer edges of said wings, as illustrated by Figs. 1, 4,and 6.

The modified form of the hasp D illustrated in Figs. 7 to 9, inclusive,differs from the preferred form in not having ribs d or theforwardlyextending wing d4, which wing,though it adds strength to mydevice, is not essential to its operation, and when said wing is omittedthe curvature of the front side d8 of the head is ordinarily immaterialand may be omitted.

D3 represents an arm extending down from the outer end of the hasp,which in the most complete form of my device, Figs. l to (i, is providedwith a seal-wire opening dx and a loop (Z8, having a padlock-hole d9;but inasmuch as padlocks are not generally used the loop d8 may usuallybe dispensed with, as in the more simple form illustrated in Figs. 7 to9.

E represents a keeper preferably having a base e, which may be securedto the doorbatten B' by screws e or other suitable means. It ispreferably provided with forwardly-projecting parts E and E2, with aspace or slot E3 between them, as shown in Figs. l to 6, inclusive; butwhere the hasphead is formed with only one wingI d3, as shown in Figs. 7to 9, inclusive, the part E2 is preferably omitted from the keeper. Thepart E projects forward, so as to form loeneath its front edge or lip acurved recess or socket e2 for the wing d3 of the hasp-head, and itsbottom is preferably curved, as indicated by dotted lines in Figs. l and3, so as to conform substantially to the preferred curvature of the rearend edge of the wing cl3, which said socket is designed to receive. Theouter edge or lip e4 of the part E is also preferably curved outward inthe arc of a circle substantially parallel with the circle in whose arcthe outer side of the hasp-head swings and is preferably adapted to iitagainst that side of said head snugly when the seat is locked, whetherin its lowest or highest position. The edge of the lip e5 of the part E2is preferably curved inward in a Vertical plane and is preferablysubstantially parallel with the outwardly-curved lip e4 of the part E,and in the preferred form of my device it extends forward, so as to forman inwardly-curved socket e6 beneath it for the reception of the frontend of the wing d'1 of the preferred form of my hasp-head.

E4 represents a stop shown projecting forward from the face of the partE'. When the IDO hasp-head is in its lowest position in the keeper, thebottom of the hasp preferaby rests on this stop. It is preferablyprovided with a seal-Wire opening e7, which is preferably oblong inshape.

In the preferred form of my device the keeper E is also provided Withaforwardlyprojecting part E5, opposite the part E4, which is providedwith a seal-Wire opening e8, but this part, though convenient, may bedispensed With Without greatly affecting the value of my device. It isshown omitted in the form illustrated in Figs. 7 to 9.

Where the hasp is provided With the loop d8, the keeper is provided witha corresponding loop E6, designed to coperate With it and having apadlock-hole e9. Under other circumstances said loop E6 may be omitted,as in the form illustrated in Figs. 7 to 9, inclusive.

It sometimes happens that ear-doors either get slightly Warped or cannotbe completely closed for some other reason, and under such circumstancesand when the hasp-head cannot be forced down as low as the position inwhich it is shown the preferred oblong form of the seal-wire openingsprevents there being any difiiculty in inserting the seal-Wire. lVhereno padlock is used, the seal-Wire may in the form shown in Figs. l to 6be passed through the padlock-holes hereinbefore described. So, also,the seal-wire may be passed through the padlock -hole d and the seal-Wire hole e7 in case of necessity. On account of the curved form of theslot ez and the hasphead the latter lits the slot in the keeper-headsnugly in all positions, and when the hasphead is seated in its slot theusual strains upon the hasp have no tendency to unseat it or break theseal. The movable pin ordinarily used in ear-seals is entirely dispensedwith, and the hasp and keeper may each be and preferably are cast in onepiece. v

I claim- 1. In a seal-lock, aha sp having an inturned head, abackWardly-extending wing carried by said head, a forwardly-extendingWing also carried by said head, a keeper having two outwardly-turnedmembers, a forwardlyextending Wing carried by one of saidoutwardly-turned members, and a rearwardlyextending Wing carried by theother of said outwardly-turned members, said Wings coperating with theWings carried by said head.

2. In a seal-lock, a hasp having an inturned head, a keeper having aforwardly-opening slot for engaging With said inturned head, aforwardly-projecting member carried by said keeper, saidforwardly-projecting member being provided with a seal-wire opening andacting as a stop to limit the movement of said hasp, and adownwardly-projecting member carried by said hasp and provided With aseal-Wire opening adapted to register with the said first-mentionedseal-Wire opening.
